First of all, I apologize if this kind of styling help or scripting help is deemed inappropriate for this forum. I will take this down if necessary.
What I would like to achieve is to have a fixed size/style of post-card on the blog front page of the casper theme. It seems that by default, the post-card adjusts its size (or perhaps better described as shape) to fill the page horizontally (See here for example). Where and how could I modify the theme to have a fixed shape of the post-card. Since it is dynamic, I am guessing it’s part of a JS script. But I am having trouble locating where it is.
Thanks for any help in advance!
